This device is there to protect important networks from direct lightning strikes and back flashovers. Indented to be installed along the protected line, it works perfectly on distribution (sub-transmission) lines with the highest voltage of equipment up to 52 kV.
This product operates on the basis of EasyQuench technology.
d45z can easily be adapted to poles/towers of totally different configuration. This is possible due to various installation options.
- Highest voltage for equipment, 52 kV
- Protects from Direct Lightning Strike
- Protects from Back Flashover
- No maintenance is required
